Using the Sample Size button
The Sample Size button provides options for choosing how
extensively the color information will be read — whether the
color information will apply to a pixel, a 2-pixel by 2-pixel
area, or a wider expanse (maximum 5-pixel by 5-pixel area).
When you click on the Sample Size button, the drop-down
menu below appears:
Determines the size of the
sampling area
Determines how the numbers in
the Color Meter Display are
shown — in absolute values or
in percentages
Value and Percent
• If you choose Value, the numbers in the Color Meter
Display represent the values in the 0-to-255 pixel scale. For
instance, an R value of 23 indicates that the sampling size
selected has a red color value of 23. Value is calculated by
multiplying the percentage by the constant 255 (value =
255 x percent).
• If you choose Percent, the numbers represent the percent-
age of the maximum intensity of the pixel. For instance, a
G value of 35% indicates that the sampling size selected
has a green color value to be 35 percent intense (out of 100
percent). Percent is calculated by dividing the constant 255
by the value (percent = 255 ÷ value).
